TRUCK PEDESTAL.

Application file-:1 July 7, 1928.

This invention relates to railway car trucks and more particularly tothe construction of the pedestals secured to the wheel pieces or sideframes of such trucks.

It is a general object of the present invention to provide a novel andimproved pedestal construction and assembly for use on railway trucks.

More particularly, it is an object of the invention to provide in arailway truck pedestal a pedestal leg slotted for its full length toallow the insertion of an equallzer together with a novel pedestal strapprovided with a spacer or reinforcing member for the slotted leg.

One of the features of the invention comprises the arrangement of apedestal liner to be engaged between the bottom of a slotted pedestalleg and the pedestal strap and having means thereon to engage with theend of the strap to retain the liner in position.

Other and further features and objects of the invention will be moreapparent to those skilled in the art upon a considera tion of theaccompanying drawings and following specification, wherein is discloseda single exemplary embodiment of the invention with the understanding,however, that such changes may be made therein as fall within the scopeof the appended claims without departing from the spirit of theinvention. 7

In said drawings:

Figure 1 is a side elevation of the end portion of a side frame or wheelpiece of a railway truck showing a pedestal and the end of an equalizerbar adapted to rest. on top of the journal box carried in the pedestaljaw;

, Figure 2 is a transverse vertical section on the line 22 of Fig. 1; V

Figure 3 is a partial view similar to Fig. 1, but showing the liner inlongitudinal section and with one branch of the pedestal leg removed;

Figure 4 is a horizontal section on line H of Fig.3; and

Figure 5 is a perspective view of the lower end of a liner.

In a large number of four-wheel railway trucks'it is customary toarrange equalizers with their opposite ends resting on the journal boxesat each side of the truck. The wheel pieces or side frames which supportthe car body through the body bolster are Serial No. 291,942.

supported from the equalizers by springs (not shown). These side framesare pro vided with pedestals to position and guide the journal boxeswhile allowing them vertlcal movement. This type of construction is wellknown. The six-wheel trucks often have a somewhat similar arrangement,using two equalizers to a side, however. In both cases itvis difficultto introduce the equalizers through the slots provided for the same inone leg of each pedestal. The present invention contemplates openingthis slot from top to bottom of one of the customary slotted legs foreach equalizer. The equalizer can then be applied by inserting pne endinto the short incomplete slot and lifting the other end through thecomplete slotjust described. This materially simplifies the assemblyoperation, but tends to also weaken the pedestal, for the branches ofthe slotted leg are not secured together. The present invention provideson the customary pedestal strap or tie bar a projection to extendbetween the arms or branches of the slotted pedestal leg and to receivea transverse securing means passing through these branches. Thisproject-ion acts as a spacer or reinforcing member and the securingmeans which holds it in position also retains the pedestal strap inplace.

Referring to the drawings, there is shown at a side frame or wheel pieceof a railway truck. In this particular embodiment the pedestal 11 iscast integral therewith and is of hollow box-like construction as arethe members of the side frame or wheel piece. The pedestal has the legsv 12 and 13. In the four-wheel truck the leg 12 would be closed, i. e.,would not have a slot to allow the insertion of an equalizer between thetwo sides of the leg. The inner face thereof, or the one which wouldnormally engage the journal box, is solid in the leg 12. The leg 13,however, is slotted as shown at 15 in Figures 2 and 4 so that it isdivided into the two side branches 16 and 17 open from the junction 18of the leg with the frame clear to the bottom so that the equalizer 19may have its end merely lifted into the position shown in Figure 1between the branches 16 and 17, which act as guides to prevent lateralmovement of the equalizer. Suitable reinforcing ribs 21 are provided onthe outside of each branch of the leg and those 22 and 23'on the inside.As shown in Fig. 2,

' strap and through the base or foot 28 of the jaw while the hooked end29 of the strap engages the end of this foot to assist the bolt inpreventing any spreading of the jaw.

The opposite end of the strap, which in its main portion has arectangular cross section of the width of the bases of the legs, passesbeneath the portions and has the reduced upstanding portion 30 whichpasses between the portions 25. it has at its upper end the relativelyheavy and wider sleeve 31 the ends 32 of which engage against the innersurfaces of the branches of the leg 13 shown in Figs. 2 and l. A bolt 2apasses through suitable openings in the branches and through the bore ofthe sleeve 31 and retains the sleeve in position. This sleeve acts as aspacer and reinforcing means to hold the branches of the leg spaced inposition and at the same time the bolt 3a acts to prevent relativespreading of the two legs of the aw. It is assisted in this by thesleeve abutting the ribs 23 as shown in Fig. 1. Beneath the verticalextension the wide portion of the strap terminates in the rounded ends36 as shown in Figs. 1 and 3.

It is desirable that the movement of the box in the pedestal shall notwear directly on the pedestal legs, so suitable liners, preferably ofhardened steel or similar material, are arr nged to protect the innerfaces of the jaws. On the leg 12 this liner takes the form of a sheethaving the section 37 resting against the inner face of the jaw andarrangedto take the wear of the box. Wings 38 engage the sides of theleg to prevent lateral movement of the liner in respect to the jaw andto take the lateralthrust of the box. A tongue 40 projects at rightangles to the part 87 and beneath the base 28 of the leg and between itand the strap shown. This tongue is perforated to allow for the passageof the bolt 27. The tightening of this bolt clamps the tongue inposition and the en: gagement of the bolt with the sides of the holeinthe tongue prevents any longitudinal or lateral movement of the liner.

' The liner l1 onthe slotted le is somewhat similar in construction tothat on the other leg, but its face 42 must be slotted near the top toallow for movement of the equalizer,

it being understood that the liner is applied after the equalizer is inposition. 7 The liner 41 has wings as in the one just described, and asomewhat similar tongue 43 which is best shown in Fig. 5. The end of thetongue is slotted as at at toprovidethe arms 45. The portion 13 togetherwith the arms is received between the bases 25 of the branches of theleg and the strap 26, but since the bolt 34 is horizontal instead ofvertical, the clamping action here cannot be relied upon to retaintheliner in position. The arms 45 therefore engage opposite edges of theextension 30 on the strap to prevent lateral movement of the liner. Theends ofthese arms are turned down as at 47 so that they engage aroundthe curved end portions 86 of the strap, thereby preventing anylongitudinal movement of the strap in the direction of the oppositepedestal leg.

By making the spacer integral with the pedestal strap, a materialreduction in the cost of manufacture and in the operation of assembly isefiected and by arranging the liner to cooperate with the strap andspacer, no added means are necessary to retain it in position and theoperation of assembly is eX- tremely simple. At the same time, theconstruction is j ustas efi ective as those of much more complicatedarrangements and the cost of manufacture is materially reduced.
